Did you ever have one of those friends who you were embarrassed to be around but too subdued to send them away? Ever meet a new friend and become engaged in a conversation for what seems like a millisecond when that embarrassing person rounds the corner and tries to butt in? If you do, then you know that subsequently the new friend drifts off. It's pretty horrid when you think about it, and a sure way to be a loner through something called high school.
As you know by now, bad friends exist. Unwanted friends exist. Friends who aren't really friends - they're out there too. That's why your argument is completely worthless when you try to side with them. It's obvious from the way you speak of them that you don't like them, so DON'T USE IT AS AN EXCUSE.
"Oh, it's okay that you're a lesbian. I totally have a lesbian friend...!"
At least try to make it convincing. Sheesh.
